HINGED CAP.

Application filed December 4, 1922. Serial No. 604,951.

- the cap is used so that the latter may \not become lost. The fastening means is particularly designed to be used for the cap of a gasoline tank of a motor vehicle but the invention is not confined to that particular use and protection is sought on the novel features disclosed in the following specifi cation irrespective of the particular use to which the same is put.

The preferred form of the inventionis illustrated in the accompanying drawing in which Figure 1 shows a side view of the upper portion of a tank having my cap secured thereto, Figure 2 a top plan view of my cap and its holding mechanism and Figure 3 a side view similar to Figure 1 and showing the cap in section. While I have shown only the preferred form of the invention it should be understood that various changes or modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

The tank (1) which may be used for any suitable purpose as for instance for a gasoline tank for a motor vehicle is provided with a neck (2) threaded at its upper end as shown at (3). The threaded portion of the neck is adapted to receive a cap (4:) threaded internally as shown at (6). The cap is provided with a flange (7) adapted to loosely engage an annular groove (8) in a ring (9) which latter is split as shown at (11) in Figure 2 and terminates in two parallel lips (12) adapted to receive between the same the lug (13) of a link (14). A pin (16) passing through registering perforations in the lips and the lug pivotally connects the link with the ring.

A stationary projection (17 extends laterally from the neck (2) and has a second link (18) pivotally connected thereto as shown at (19). (18), the combined length of which exceeds the length of the neck above the pro- The two links (14) and jection (17) are pivotally connected with one another as shown at. (21).

It will readily be seen that thecap in order to be placed on the neck must first be positioned in axial alignment with the. same. The pivotal link connection between the projection (17) and the ring (9) does not interfere with this part of the operation since the combined length of the two links (1 1) and. (18) exceeds the length of the neck extending above the projection (17) The fact that the engagement between the flange (7) i and the ring (9) is rather loose allows the cap to be turned for the purpose of securing the same on the neck without necessitating a corresponding rotation of the ring (9), which latterof course has to maintain its original position since the particular link connection to the projection (17) would prevent the same from turning. The latter connection however does not interfere with a downward motion of the ring (9) and allows the same therefore to move downwardly with the flange of'the cap. If it is desired to remove the cap it is only necessary to turn the same in the opposite direction and after it has become disengaged from the threaded portion of the neck the links (14:) and (18) will hold the same so that it will not be lost.

It should be added that various details can be arranged differently without departing from the scope of the invention and particularly that the projection (17) instead of extending laterally from the cap may project vertically from the tank..

I claim:

1. Fastening means for a cap engaging a port member in an axial direction, comprising a, ring loosely fitting on the cap, a tongue and groove engagement between the cap and the ring, and flexible means for securing the ring to the port member, comprising links pivotally engaging the cap and the port member, and a pivotal engagement between the links.

2. Fastening means for a cap engaging a port member in an axial direction, comprising a ring loosely fitting on the cap, a tongue and grooVe engagement between the cap and the ring and flexible means for securing the ring to the port member, comprising a pair of lips extending from the ring in spaced relation, a link pivotally engaging the same, a lug extending from the and a pivotal engagement between the links. 1

3. Fastening means for a cap engaging a port member in an axial direction comprising a flange on said port member, a ring havlng an annular groove therein adapted to loosely engage the flange, and flexible means for securing the ring to the port member.

4. Fastening means for a cap engaging a port member in an axial direction comprising a flange on said port member, a rin having an annular groove therein adapted to loosely engage the flange and flexible means for securing the ring to the port member, said means including links pivotally engaging the cap and the port member, and a pivotal engagement between the links. 5. Fastening means for a cap engaging a port member in an axial direction comprising a flange on said port member, a ring having an annular oove therein adapted to loosely engage t e flange and flexible means for securing the ring to the port member, said means including a pair of lips extending from the ring in spaced relation, a link plvotally engaging the same, a lug exending from the port member having a link pivoted thereto, and. a pivotal engagement between the links; 4 Y
